Hi Haroon,
A disk marked as FORMER can be safely added to a new diskgroup, as this
status means that the disk was cleanly removed from an old diskgroup. As
per the 11.2 documentation:
"From the perspective of the installation, candidate disks are those that
have the CANDIDATE, PROVISIONED, or FORMER header status. These disks with
a CANDIDATE, PROVISIONED, or FORMER status can be added to Oracle ASM disk
groups without using the FORCE flag."

Kind Regards,
Lucas Pimentel Lellis
